Title: Method of testing article before welding
Inventor: ROOMAN HAASHITSUZU
IPC: H01L21/60
Filed: 1989-07-19
Abstract: PURPOSE: To perform high reliable welding between sheet metals of conductive material by measuring resistance in the vicinity of a zone to be welded between sheet metals lapped for welding, and comparing a measured value with a predetermined value. CONSTITUTION: Two sheet metals of conductive material are touchingly arranged in a zone to be welded. Next, a first and second electrodes placed over an area to be welded are brought into contact with the top face of the upside sheet metal. A small electric current is caused to flow between these two electrodes to measure a resistance. When this measured value exceeds a predetermined value, contact condition between the sheet metals and the electrodes is improved. Secondly, a resistance between at least one of the first and second electrodes mentioned above and a third electrode which is brought into contact with the lower sheet metal in the place adjacent to the area to be welded is measured.  When this measured value is compared with the predetermined value and is smaller than the latter, the both sheet metals are welded by supplying electric welding energy between the first and second electrodes. On the other hand, when the measured value mentioned above exceeds the predetermined value, the vicinity of a zone to be welded of the both sheet metals is applied with cleaning treatment, and welding is performed under condition in which a measured value is smaller than the predetermined value.

Abstract: PURPOSE:To require only one mask, to decrease resist processes by one time and to simplify a manufacturing process by forming an isolation region between a polysilicon layer under a resist and a p<+> layer, to which B is implanted, by isotropic-etching the polysilicon film and diffusing P contained in the polysilicon film to a substrate on annealing. CONSTITUTION:An oxide film 11 is shaped onto the surface of an n-type Si substrate 10, and polysilicon containing P is deposited onto the oxide film. The upper section of the polysilicon film 12 is coated with a resist 13, a region as a light-receiving section is patterned, the polysilicon film 12 is anisotropic- etched vertically through RIE, and B ions are implanted while using the resist 13 and the polysilicon film 12 as masks. The polysilicon film 12 is isotropic- etched as the resist 13 is left as it is. Consequently, isolation regions (t) are shaped among p<+> regions, into which B ions are implanted, and the polysilicon film 12. The resist is removed, and the crystallizability of the B-ion implanting sections is recovered through annealing while P included in the polysilicon film 12 is diffused to the substrate and n<+> layers as the isolation regions are formed. Accordingly, a manufacturing process can be simplified.

Title: Method for selective electric fluorination of uranium based alloy or metal mixture
Inventor: IBU BERUTOO
IPC: C25B9/19
Filed: 1993-06-29
Abstract: PURPOSE: To selectively recover uranium in the form of a fluoride by subjecting at least one component of an alloy to a selective anode reaction with a bath of the molten fluoride.  
     CONSTITUTION: A cathode block 4 is separated from the remaining part of a cell (anode block) by a diaphragm 5. The bath is circulated via a coiled hose 2 and melted at 120°C and cold air is forcibly fed into the coiled hose 3 at the bottom of a tank 1, by which the bottom coated with the layer of a solidified bath 23 is formed. Voltage is impressed between a cathode terminal K an anode terminal D and the selective dissolution reaction is controlled by taking the selective dissolution voltage of the uranium and the overpressure and resistance of the apparatus into consideration. While the resulted resistance loss is compensated, the voltage is maintained constant and the regular supply of HF is executed in such a manner that the specified HF content of the bath is maintained. The captured gas is constitutionally formed by UF 6 .
